-Monocot and Dicot Coloring
Bellringer
Briefly tell the function of the 3 parts of the plant cell that are unique to the plant cell.
Are plant cells eukaryotic or prokaryotic? Explain how you know this

4. Propagation Lab
Make sure the date is written next to your first drawing
Measure your stem
Record surface area of ALL leaves!
Count a partial square if it is at least half covered by the leaf; do not count partial squares that are less than half covered.

5. Objective
You will be able to name and provide characteristics of the 4 plants groups
You will be able to explain the difference between monocots and dicots

6. Plants!!
Botany = the study of plants!

7. Overview of Plant Kingdom
Botanists divide the plant kingdom into four groups
Flowering plants (angiosperms)
Cone bearing plants (Gymnosperms)
Ferns and relatives (seedless vascular plants)
Mosses and relatives (Bryophytes)
Based on 3 factors:
Water-conducting tissues
Seeds
Flowers
Today plant scientists can classify plants more precisely by comparing the DNA sequences of species.

8. Bryophytes Low growing plants found in moist, shaded areas.
Lack vascular tissue, therefore these plants use osmosis to draw water up a few centimeters above ground.
3 groups
Mosses
Liverworts
Hornworts

9. Seedless Vascular Plants
Have true roots, stems, and leaves.
Have specialized tissue that transports water and sugar.
3 groups
Horsetails
Club mosses
ferns

10. Gymnosperms Conifers (Christmas trees!)
“naked seeds”- cone bearing plants (seeds grow on cones)
Needle like leaves
Usually stay green year around
Wind pollinated
Examples: pine trees and evergreens!

11. Angiosperms Flowering plants Seeds are enclosed in a fruit
Most are pollinated by birds and bees
Have finite growing season
Examples: grasses, tulips, oaks, and dandelions

12. Angiosperms are divided into two main groups:

13. Dicots:

14. Monocots:

16. Parts of the Plant Roots/ Stems/ Leaves Roots:
-Water and minerals are absorbed
Also used to anchor the plant

17. Stems Transports water and nutrients Support plant
*Two types: herbaceous and woody

18. Leaves
Photosynthetic organ of the pant, used to convert sunlight into food!
Photosynthesis:
Carbon dioxide + water = Sugar + oxygen
